The world produces around 16 million tons of copper per year now.(2008)
The accepted estimate for global copper reserves is 1,600 million tons
of which only 900 million tons are economically viable.
* at our present rate of extraction , drill-able copper will run out in 61 years * with a modest growth of 2% annual increase in extraction drill-able copper will run out in 25 years
* copper is rare enough to be 8.24US$ per kilogram average in the last 10 years (2.43US$ now due to the slow down) PS: if your asking about percent of matter on earth that`s copper it`s a tiny

Copper is an element also known as CU on the Periodic Table. It is extremely common on earth for it can be found deep in the earth but as well it can be found seeped into the soil on the surface of the earth.
Copper isn't only found in the earth, it is also found in living things, and it plays a role in our bodies, and in those of animals.
>more information can be found about purpose of copper(in our system etc)
copper is common because its in nickels, zinc, gold, and Molly so its very common. Its also used for wiring houses it helps with the electricity
I think copper is common but I am not entirely sure. Hope this helps!
Copper is rather common. There are an estimated 1014 tons of it left, however, the cost of mining it all far exceeds the economic valule of doing so.
I think i found some copper today in my backyard is that possible?
yes it is hard to find
6.0×101 milligrams per kilogram
It is very very rare for a solid copper quarter worth maybe $800 +
No isotope of copper ordinarily found in nature is radioactive. Like all elements, synthetic radioactive isotopes of copper exist.
Although US one-cent coins (pennies) were once mostly copper, today they are 97.5% zinc with a copper plating. Copper nails are rare due to the metal's malleable nature, but zinc nails can be plated with copper as are pennies. Brass is an alloy of copper and zinc, and is widely used.
If you mean a coin blank that has not been struck, but still has its copper coating, that's called a "flan" and is only worth about $1. If you mean a coin that has been struck with the Lincoln images but does not have its copper coating, you'll need to have it examined in person. If the missing copper is due to being dipped in acid, the coin is essentially worthless. But if it came from the Mint that way it's a fairly rare error that could be worth up to $100 retail.

No
Yes it is very rare
It is very very rare for a solid copper quarter worth maybe $800 +
it is rare and found in porphyritic only
mushroom cannons but its rare
No, not at all, it's very common.
$35,000.00 to $81,000.00
diamonds were really rare in the copper age because no one had really discovered them yet
-In 1943, pennies were made out of steel instead of copper. A 1943 pure copper penny is a rare mint error, and is worth lots.
Silvers family name is either the copper group (copper is the lightest memeber of group 11 in the perioic table) or the coinage metals, copper silver and gold were long used to make coins. The rare earths are scandium yttrium and the lanthanides, 17 in all.
Yes there are 1831, 1834 and 1837 in high grades....1837 is quite rare 1841 with a colon after lettering REG on the reverse 1843 1849 1856 1860 over 59 (about 400 struck) - extremely rare These are the best known of the rare copper penny dates.
They are rare but bluish-green formations are known. The minerals responsible are copper salts.
